Question

Central dogma- what is it? Is it a theory or a flow (of information)?

From Crick's words as given in wikipedia :https://en.wikipedia.org/wiki/Central_dogma_of_molecular_biology it sounds like both a theory and then a flow (kind of a process).

P.S. I understand what it means but not what it is.

Answer 1

The Central Dogma is a theory. It describes the process of information passage from DNA to protein through RNA.
